Chapter 1: Weather
Mr. S 4th Grade
| Question | Answer |
|---|---|
| What affects the temperature of the air? | How much light energy from the sun reaches the Earth. |
| Which sunlight, direct or indirect, causes highter temperatures? | direct |
| What time of day is the temperature usually the lowest? | before sunrise |
| Does more daylight cause higher or lower temperatures? | higher |
| What time of day does sunlight hit the earth most directly? | noon |
| Why is pavement hotter than grass? | because it absorbs heat |
| What happens to the alcohol in the thermometer as it gets hotter?why? | when the air around the tube is hot the liquid will rise |
| Which color absorbs more heat? | black |
| What is Air Pressure? | Pressing down of the layer of air that surrounds the earth |
| How is a low pressure area formed? | When the air gets warmer and lighter it rises, so the air pushes down on the surface with less pressure causing a low pressure area |
| How is a high pressure area formed? | When the air gets colder and heavier it pushes down harder on the surface causing a high pressure area |
| How is wind created? | by cool air sinking and hot air rising |
| What is used to measure air pressure? | Barometer |
| how does a barometer work? | It measures air pressure by calculating how much mercury rises and falls |
| How does a gauge work? | I measures pressure by moving a pointer on a dial |
| How can you calculate speed direction? | by watching things move |
| What is a wind vane? | it is used to tell wind direction |
| What does a wind sock measure? | speed and strength of wind |
| What does a anemometer measure | exact wind speed |
| Which air holds more water vapor, hot or cold? | hot |
| Define precipitation? | moisture that falls from clouds to the ground |
| How is snow formed? | |
| What is lighting? | static electricity |
| What is a forecast? | a prediction made by a meteorologist |
| What does a meteorologist study? | Weather |
| List all the things meteorologist keep track of to predict weather? | hight and low temperatures, humidity, air pressure, precipitation, fronts, air masses |
| What tools do meteorologists use? | computer monitors and ratars |
| What does the National Weather service do? | Issues warnings and weather watches when weather conditions are right for predicting severe weather |
| What should you do if there is a Tornado? | go to inside room with no windows |
| What should you do if there is a hurricane? | leave the area and leave early |
| How do air masses move? | by air pressure and wind |
| What is a front? | where two air masses meet |
| How is a front formed? | When air masses meet,they stay separate, the line where they meet is called the front |
| What happens when a cold air mass pushes a warm air mass? | |
| what causes changes in air temperature | less or more direct sunlight |
| how do diffrent surfaces on the earth effect air temperature | becaues diffrent surfaces asorbe diffrent amounts of sunlight |
| how is air temperature measured | with a theramometer |
